Have received several calls from this number. I no longer answer numbers I don't recognise. I replied via text, saying 'Sorry to miss you. Please text and let me know how I can help.' Reply suggested the caller had a good stash of drugs. Have also received a voice mail, saying (summarised): 'Bro, meet you behind Coles.' Assuming this is a spam caller testing my number, in order to onsell it to a telemarketer list. I started getting multiple spam calls after removing my number from unlisted. I thought silent number listing only protected the landline phone, which I no longer have, so I'm disappointed to be often interrupted by calls and messages such as these (above).
